Because of weather erosion. Earth has a thicker atmosphere than the moon, say, which has no atmosphere at all, and thus, no wind, water or rain to wash away the marks left by meteors or asteroids that hit the surface of the planet. Earth is hit by things all the time, but are washed or wiped away quickly by snow, rain, wind, etc.
What else can I help you with?
What is crust?
Crust is the hard outer surface of something, typically the earth or a baked food such as bread or pie. In geology, the Earth's crust is the outermost layer of the Earth's surface, consisting of a variety of rocks and minerals.
Is crust an adverb?
No, "crust" is not an adverb. It is a noun that refers to the hard outer layer of something, such as bread or the Earth's surface.
Forms earth's hard surface?
The Earth's hard surface is formed primarily by the solidified rocks that make up the planet's crust. These rocks can be of various types, including igneous, sedimentary, and metamorphic rocks, which have been created through processes like cooling of magma, deposition of sediments, and alteration of existing rocks under heat and pressure. Over time, these rocks have combined to create the diverse geology of the Earth's surface.
Why is it difficult to determine the age of our planet"?
Determining the age of our planet is challenging because the Earth is constantly changing, making it hard to find accurate and reliable evidence of its age. Additionally, the processes that shape the Earth's surface can erase or alter older materials, further complicating the dating process.
Why are minerals that form below Earth's surface unstable at Earth's surface?
Minerals that form below Earth's surface are unstable at the surface because they are often formed under high pressure and temperature conditions, which are different from the lower pressure and temperature conditions found at the surface. As a result, these minerals can undergo chemical reactions or physical changes when exposed to the new environmental conditions at the surface, causing them to break down or transform into more stable minerals.
Why do you see several impact craters on the earth but few on the moon?
There are relatively few craters identified on the surface of the Earth while there are thousands (millions) on the moon. It is hard to find one point on the moon that is not in one crater and there are craters in craters in craters. (See images in related link for Moon.) Obviously, the major reason behind this is that the craters that formed on the Earth eroded over time due to wind, rain and other natural factors which are nearly absent on the moon. Thus Earth's craters disappear over millions of years while the craters on the moon remain for billions of years. (The primary way a crater is made to disappear from the surface of the moon is by having another impact crater formed and the dust and debris from later impacts disturb or destroy or cover the original crater.)
Does earth have many craters?
Yes, they are hard to detect without orbital photography though.
Is the moon soft or hard?
The moon's surface is solid and rocky, so it is not soft. It is covered in craters, mountains, and dust.
If you drop marbles into a pan of sand what would you be simulating about the Moon's surface?
By dropping marbles into a pan of sand, you would be simulating the impact craters that form on the Moon's surface due to meteorite collisions. The craters are created when high-speed objects strike the Moon, displacing the surface material and creating a depression.
If you drop a marble into a pan of sand what would you be simulating about the moons surface?
that it would be like the craters on the moon and that it is very hard.
Why does the earth have less impacts than the moon?
The answer is that the Earth has more meteoroids hitting it, but most do not survive to impact the surface. The Earth has a protective atmosphere that burns up a lot of meteors. Most others are slowed enough that they don't make a big crater. The ones that do make it to the surface may fall into water, which covers 3/4 of the planet, and these craters are hard to locate. For land impacts, the actions of the atmosphere (rain, winds etc) erode the impact craters, as does geologic and volcanic action. So what we see are only a tiny number of persistent craters that have avoided obliteration. The Moon does not have any of these forces at work, so almost all of the impacts since the moon was formed can be seen on its surface. The major changes in the craters are made by later impacts at the same locations.
How might the moon craters and rilles have formed?
Moon craters are mostly formed by impacts from meteoroids, asteroids, or comets striking the moon's surface. Rilles, on the other hand, are thought to be formed by lava tubes or collapsed lava channels from ancient volcanic activity. Both features give us information about the moon's geological history.
Which make up the hard and rigid surface of the earth?
The lithosphere makes up the rigid surface of the Earth.
The material that forms Earth's hard surface?
rock
What forms Earth's hard surface?
Constructive Force
What is name of the hard rocky surface that covers earth?
crust
Why are craters harder to see on earth then on the moon?
Air and water will gradually transform the craters, making them hard to see. The craters will be "washed away". On the Moon, it takes much longer for a crater to become "washed away".Air and water will gradually transform the craters, making them hard to see. The craters will be "washed away".
